RMA42 process indicator with control unit

Field of Application

The RMA42 process transmitter displays, evaluates, and calculates analog measured values. It features an integrated loop power supply (LPS) for powering two-wire sensors. Its universal inputs allow for the connection of current, voltage, RTDs, and TCs. Limit values can be monitored, and relays can be switched accordingly. Process signals can be forwarded via analog outputs. The integrated "differential pressure" application package enables quick and easy commissioning for differential pressure applications.

The RMA42 transmitter includes:

• A clear display
• Analog inputs for process and status signals
• Analog and digital outputs
• An interface for configuration

All measured and calculated values can be used as signal sources for display, outputs, relays, and interfaces.

Applications

• Plant and apparatus engineering
• Control rooms and cabinets
• Process control, recording, and supervision
• Signal adjustment and conversion
• Overfill protection (WHG)

Benefits

• Enhanced safety – Optional SIL 2 approval
• Marine-ready – Approved for offshore and marine applications
• Advanced calculations – One or two calculated values with a linearization table
• Data storage – Min/Max value storage for process analysis
• High-visibility display – 5-digit, 7-segment LC display with backlight
• Flexible sensor connections – One or two universal inputs
• Switching functions – Optional two relays
• Digital status output – Open Collector output for process control
